Further on my meals (brought over from the Chat thread as it seems better here). Stand by for some pretty excellent analysis ...
... I've realised that if M2 and M4 are fixed (apple and cottage cheese), and M1 is fixed (muesli, berries, cc, wheatgerm, milk) and M3 could be fixed as it always used to be (tin o' fish, large amount of salad) then that just leaves M5. And portion control can be used on that. Plus lots of water, some tea and some coffee.
This is the plan on which I lost weight. I could do that again. Obviously I decided I could go off-piste for a bit and explore some hidden highways and byways of omelettes, nuts and so on. Back to the straight and narrow for me, I think.
Further thoughts circle around how things cannot be unlearnt (see JayEll's comment upthread). There were many things I didn't know about until I came to 3FC. Part of that is connected to our 'shared' language which is so different in different parts of the world, I suppose. 'Baked goods', for example, are something I learnt about here, having always dismissed them as 'shop cakes'. I still think they are horrible but I have eaten them now. Before I came to 3FC I never ever thought I would. Correlation does not imply causation, of course, but I'm a bit suspicious. I still could never eat fast food, though.
So, to reiterate for my benefit, Ms 1,2,3,4 are fixed. Portion control for M5. It's quite a nice plan. Roll on tomorrow!
